The Manniu engine mentioned at this time is the water-cooled machine shared by the Tornado III single-engine version and the Manniu propeller type, with a power of 1080 kilowatts.

Three times that, which is a minimum of three megawatts.

However, unlike the radial engine, the turboprop engine is a hybrid, with both shaft transmission and jet thrust. It is not easy to get a more accurate power value, and it can only be changed to thrust. This point is directly from the part of the fixed engine. The force on the structure can be measured, about 180 kN.

To put it into perspective, almost two engines can drag a 38-ton aircraft and keep it stationary in the vertical direction.

Of course, this is just a meaning. In fact, turbine engines are not suitable for such actions. They must be moved before there is power in the engine.

On a medium-low speed aircraft flying normally, two 180 kN engines can probably make a 55-ton aircraft take off, which means that the aircraft can be made larger while the number of engines remains unchanged.

Wang Qi's expectation for it is to break through the air force's speed bottleneck.

In the world of martial arts, the only thing that is fast is unbreakable, and it is just right on an airplane.

The most famous reconnaissance aircraft in the previous life was the Blackbird. It can be said that it was full of shortcomings. Its only advantage was that it was fast. During its service life, no contemporary missiles could catch up with it.

The same is true in the magical world. The kingdom's research institute system and private research system have compiled statistics on factors such as the casting time, projectile speed, and the distance of direct-effect magic of most magics.

It can be said that for every two hundred kilometers per hour increase in speed, 70% of the magic attack will be eliminated.

This means that after the speed exceeds 600 kilometers per hour, all magics from low-level to high-level are classified together, and only less than 3% of the magics have a chance to threaten the fighter.

Having a chance to threaten does not mean that a hit is certain. This also depends on factors such as individual reaction speed, magic characteristics, accurate calculation of lead time, and changes in aircraft movement.

The turboprop engine can relatively easily increase the flight speed of the aircraft to more than 700 kilometers per hour. If its survival rate can be confirmed on the battlefield, the Air Force can consider operations in the form of squad formations, which can further expand the Air Force's tactical space.

In addition, the propeller driving force of the turboprop engine comes from the gas turbine, so it will have better adaptability to high altitudes, allowing aircraft equipped with it to generally fly to an altitude of 10,000 meters.

Oh, by the way, pressure altitude should be used now.

Based on the current surface air pressure of 1100 hectopascals, the working characteristics of the turbine can allow it to maintain a relatively stable flight in the range of 250 to 300 hectopascals, which is about 10,000 to 11,000 meters from the surface of the floating island. Due to high altitude resistance When the effect is reduced and the engine power decreases to a limited extent, the flight speed will be faster than at medium and low altitudes.

The problem is still molybdenum steel.

The current molybdenum cannot be mass-produced and is mainly provided by the alchemy studio. Moreover, unlike the rubber used before, molybdenum is also useful in the magic field, so the alchemy craft formula is guarded more closely.

But it’s not a big problem, just add more money.

In fact, there are magic talent output institutions like the Magic Academy. It is difficult to keep the secret recipe of alchemy. If you really add millions, you will not let go. Throwing money into the Magic Academy will produce results sooner or later, and the results here will definitely be there. If it is made public within the department, the whole world will know about it in a few years.

In short, as long as the aircraft can be finalized, other external problems can be solved.

Wang Qi and Li Xiang visited the engine test and then went to the wind tunnel area to see new models.

The wind tunnel area of ​​Blue Sky Heavy Industry has its own small workshop, which specializes in making wind tunnel models according to the drawings. If there is a workshop, it is natural to have office staff. The wind tunnel is more than 100 meters away. The middle is very empty, mainly for noise reduction.

I took a look around the wind tunnel and went to the office to look at the model.

"Your Majesty, the display racks have been blown through the wind tunnel, and the glass cabinets should be familiar to you. They are all those that have served. There are also some that were not sure whether they could successfully pass the durability test and did not have time to be blown, so they are still drawings." Introduction It was a bit embarrassing, "The models that match the new engine are all dual-engine models for the time being. We still have some problems with four-engine and single-engine models that we haven't figured out yet."

"It doesn't matter. Take your time. Put one into production first and see the effect on the transportation line or on the battlefield."

There are only a dozen models on display racks and cabinets in total. Excluding the glass cabinets, there are four that have been blown through the wind tunnel.

The proportions of the models here are fixed, and the size can be seen intuitively.

Although twin-engine power can theoretically carry heavier aircraft, the design is still relatively conservative, and the largest one is slightly larger than the Manniu.

In addition to the difference in size, the airfoils of several models also differ greatly. The largest one has a straight lower wing, and the smaller the wing, the greater the sweep angle.

"Have you communicated with the garrison?"

The man on the other side nodded, took two steps forward and picked up one of them: "This one has been modified according to the requirements of the military."

It happens to be the smallest of the four models that have been blown through the wind tunnel.

It's not a surprise. Whether it's reconnaissance or combat, the military will definitely prefer speed advantage. Under the premise of using the same engine, the smaller the aircraft, the greater the thrust per unit weight.

But it's not very small in comparison.

The maximum length of each model in the Tornado III series is only 11.5 meters. The size of this model is visually estimated to be over 16 meters in length.

The reason why the plane is bigger is because the new engine is too powerful. Small planes use twin engines and are too close to the cockpit. Noise, vibration and safety threats are all problems.

Wang Qi looked at it and saw that someone had already handed over the corresponding drawing of the model.

Of course it was a simple structural diagram. Wang Qi didn't have time to look at the too detailed drawings.

The interior structure of this aircraft is very unique. Its passenger area has four double-decker seats... and a toilet.

The drawing also explains the functions of the crew, including a main pilot, a co-pilot and weapons division, a ground observer, which is equivalent to the original reconnaissance observation position, and the fourth is the communications and second weapons division.

There are too many part-time jobs and I feel like I can’t work.

But thinking about it carefully, there is no particularly good way. After all, the industrial system is too small, and there are too many aircraft models that the production side cannot take care of.

Wang Qi pointed to the toilet: "What did the military say? Why is this on combat aircraft?"

On a civil aviation aircraft, a toilet would not be out of place, but multiple toilets on smaller combat aircraft would take up too much space.

"They said that sometimes flying in the sky takes too long and suffocates people. They asked us to think of a solution."

"...If you want to change it, I'll talk to them later." Wang Qi thought about it but still felt it couldn't be done.

In the past, the long time in the air was mainly due to the slow flight of early aircraft, especially the gliding type. A reconnaissance mission took more than six hours.

But the new engine will make the plane faster, and the time in the air will be shortened, which will create an extra facility.

I really can’t use a urine bag!

Before deciding on the model, we need to maintain communication and have a casual chat in front of us.

The difficulties encountered by Blue Sky Heavy Industry in four-shot and single-shot are not difficult.

The four engines are mainly a wing wiring issue. Both engines have not landed yet, so it is too early to talk about that.

As for the single shot...this is a bit technically difficult.

From front to back, the turboprop is the propeller, reduction transmission gear, turbofan jet engine body, and tail nozzle.

If you want a single engine, it is impossible to turn the engine upside down and set the propeller at the tail end, because the turbofan must take in air from the direction of flight and enter the process of supercharging, combustion, and injection, and the drive shaft of the rear propeller cannot be arranged.

The biggest problem with placing it on the nose of the aircraft is that the only option for the tail flame is to come out from the side, and in front of the driver's face, placing it under the wing will also affect the aerodynamic lift and affect the observation from the front.

Swinging it sideways means that the wake thrust cannot affect the balance of the aircraft body. In fact, the only option is to reduce the size of the engine, reduce the size of the engine or even discard the outer bypass, so that the wake provides almost no thrust.

In short, this engine is useless now. If you have to start from scratch with a single engine, it is better to evolve into a real single-engine turbofan fighter.
